I was happy to read today that the VisualStudio team is working on significant performance improvements for VS.NET 2005. One of the things that frustrates me most about working on Fog Creek Copilot is simply that VS.NET can sometimes be so slow that I actually lose my train of thought. Hitting a breakpoint in some of our programs can lock VisualStudio for five to ten seconds. Building the small copilot.com website can take a full minute if the master Aardvark.dll assembly has been modified. It’s like trying to maintain flow when your work environment is a series of dams. This patch can’t come out a minute too soon.
